'UNITED STATES LOUIS W'EISI-IAN, OF M'ZLVJA'UKEE, WISCONSIN.

ANTIGLAEE DEVICE.

Application filed July 13, 1925. Serial No. 43,326.

To all whom it may concern:

Be it known that I, LoUIs lVnisrIAN, a citizen of the United States, andresident of Milwaukee, in the county of Milwaukee and State oflVisconsin, have invented certain new and useful Improvements in Antiglare Devices; and I do hereby declare that the following is a full,clear, and exact description thereof.

This invention relates to anti-glare devices, and is particularlydirected to an anti-glare device adapted for use with automobileheadlights.

Objects of this invention are to provide an anti-glare device which willcooperate with a headlight to prevent rays from passing upwardly intothe approaching drivers eyes while intensifying the illuminationdownwardly towards the roadway.

Further objects are to provide a device which is equipped with aplurality of pivoted shutters, and which may be most readily adjusted tovary the angle of setting of the shutters and to thus alter the actionof the device to suit the particular demands.

An embodiment of the invention is shown in the accompanying drawing, inwhich Figure 1 is a front view of the device.

Figure 2 is a sectional view through the device.

Figure 3 is a rear view of the device.

Figure 4 is a fragmentary view showing the cooperation of the devicewith the casing of the headlight.

Referring to the drawings, it will be seen that the device comprises anannular band 1 adapted to be passed around the outer enlarged. portion 2of the headlight. This band is preferably provided with a pair of spacedapertured ears 3 at its lower end through which a clamping bolt l passesso that the device may be most readily clamped to a conventionalheadlight in a simple manner. Further, it is to be noted particularlyfrom Figures 2 and 4; that a pair of inwardly directed projections 5 areprovided preferably by deflecting a portion of the metal forming theband. These projections, as shown in Figure 1, engage the front and rearfaces of the enlarged portion 2 of the headlight and thus prevent inwardor outward shifting of the device. Preferably two or more pairs of theseprojections are formed, as indicated in Figures 1 and 2.

The upper portion of the device is provided with a widened part 6between which a plurality of shutters are each provided with rock armsor cranks 8, which are con nected by means of a vertical link 9, suchlink being conveniently formed of a sheet of metal, as indicated inFigure 23, with rearwardly struck tongues 10 which fit over the cranksor rock arms 8 of the shutters 7. {L convenient way of forming theseshutters 1s to provide a continuation of the cranks 8 in the form ofelongated bars 11 which form trunnions for the shutters and arepivotally carried in the band 1, although obviously other forms ofconstruction may be employed, if desired.

It is to be noted, further, particularly from Figures 2 and 3, that thelink 9 has a rearwardly struck apertured car 12 through which anadjusting bolt 13 passes, such adjusting bolt being either threadedthrough the upper end of the band 1 and swivelly mounted in the car 12,or else swivelly mounted in the band and threaded through the ear 12. Inthe form shown, the former construction is illustrated.

The adjusting screw 13 is provided with an upper enlarged head or thumbnut 14, preferably knurled, and if desired a lock nut 15 may also beprovided to lock the screw in position.

It is to be distinctly understood that while the device is shown as anattachment for a conventional headlight, obviously it may be built intothe headlight as a permanent portion thereof by the manufacturers.

Further it is to be noted that the inner sides of the shutters 7 may besilvercd or polished, if desired.

It will be seen that a very simple type of anti-glare headlight has beenprovided, which may be most easily adjusted and which may be locked inadjusted position.

Although the invention has been described 1 in considerable detail, itis to be understood that the same may be variously embodied and is,therefore, to be limited only as claimed.

While I have particularly shown and described a form of my invention,wherein the metallic shutters are movable and adjustable, obviously Imay, without departing from the spirit of my invention, in some casesmanufacture the invention with the shutters in one piece with the band,or in other words rigid or solid, which construction would be muchcheaper in the cost of manufacture. Thus the device can be a singlestamping, and being flexible, can readily be shaped to conform to thelight fixture.

I claim An anti-glare device adapted for attachment to a headlight,comprising an annular band adapted to surround the outer end of thecasing of such headlight and having a pair of spaced ears, means fordrawing said ears towards each other, said member havingprojectionsthereon adapted to engage said casing and prevent inward or outwardmotion of the device, said band being relatively wider at its upperportion, a plurality ofshutters mounted transversely of said upperportion and pivotally carried thereby, each shutter having a. crank armprojecting rearwardly thereof, a link joining said crank arms and havingan outwardly projecting apertured ear, and adjusting screw passingthrough the upper portion of said band and operatively coupled to saidoutwardly projecting ear of said link, whereby the angular setting ofsaid shutters may be simultaneously varied by manipulating said screw.

In testimony that I claim the foregoing- I have hereunto set my hand atMilwaukee, in the county of Milwaukee and State of lVisconsin.
